Good point.

For the target, DESTDIR is applied to the path so there's no obvious
failure.  But the location is discovered via pkg-config the behaviour
will change depending on whether cryptsetup is built before or after
systemd, so I think we need the patch below.

Subject: [PATCH] package/cryptsetup: fix tmpfiles.d setup

The configure script uses pkg-config to detect the location of
tmpfiles.d but imposes an unspecified ordering dependency on systemd.
Instead of relying on systemd being built before cryptsetup, set the
directory path explcitly, and ensure it is not set when systemd-tmpfiles
is disabled.
